Abstract

Insights

NUT carcinoma, a rare cancer, was identified with a novel YAP1-NUTM1 fusion. Treatment with gemcitabine and nab-paclitaxel showed a partial response, suggesting a new therapeutic option for this aggressive malignancy.

Area of Science:

  • Oncology
  • Genomics
  • Molecular Biology

Background:

  • NUT carcinoma is an aggressive cancer linked to NUTM1 gene alterations.
  • Current treatment strategies for NUT carcinoma lack consensus.
  • This study presents a unique case of NUT carcinoma with a non-canonical gene fusion.

Observation:

  • A patient presented with sinus pressure, a sinonasal mass, and lung metastases.
  • Initial tests confirmed NUT carcinoma but did not find a NUTM1 translocation.
  • Whole transcriptomic RNA sequencing was performed on the tumor.

Findings:

  • A YAP1-NUTM1 fusion was identified via transcriptomic sequencing.
  • An in vitro drug screen informed treatment selection.
  • The patient received gemcitabine and nab-paclitaxel, achieving a partial response lasting 9 months.

Implications:

  • Unbiased transcriptomic sequencing can uncover novel NUTM1 fusion partners.
  • Gemcitabine and nab-paclitaxel demonstrate tolerability and efficacy.
  • This combination may represent a new treatment approach for NUT carcinoma.

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists

Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy.  SP binds and activates...
